Sometimes arithmetical equations
can create really astonishing compositions. Arrangements
like the following examples are widely known.

Some examples of Pyramidal
Multiplication; they show wonderful arrangements.

Here is a novel version of this
traditional play with numbers. The challenge is to
arrange "standard" dice in a similar manner into a
pyramidal multiplication so that their top faces read
out the factors of the multiplication (multiplicand *
multiplier) and the front faces read out the correct
product. One example of a Dicey Multiplication is shown
just below.
